This invention relates to a smokers pipe and relates particularly tomeans for insuring a clean dry bowl in Aaddition to `providing a smokeltering means rso arranged that the vfiltering .medium may notbe'ignited from the bowl and at the same time may be veasily ll'ed anddiscarded.

These and other objects of the invention will 4become apparent to those`versed in the art in the following description of one particular formof the invention as illustrated in the accompanying drawing, in whichFig. 1 is a top plan view of a pipe embodying the invention;

Fig. `2, a central, vertical, longitudinal section; Fig 3, a top planview of the cleaner tube; Fig. 4, an end lView of the tube on an.enlarged scale;

Like characters of reference indicate like parts throughout `the'several views .in the drawing.

The bowl IIJ of the pipe may assume any desired form but in any event itis provided with a floor II centrally sloping downwardly to the side.thereof nearest the. pipe stem. The bowl I8 is providedpwith a vsternextension I2, herein shown as being integral Awith the bowl part Il).This stem extension `I 2 :is ybored axially to form a comparativelylarge bore therethrough and so located that 'the upper inner end of thatstem bore cuts .through and opens into the lower end of the bowl III bya comparatively small hole I3. In other words the top of the borelthrough the extension I2 is a trifie above the lowermost part ofthe-licor II in the bowl IB,

A .mouthpiece I4 is made out of any suitable material and is formed tohave a `cylindrical end I5 of a diameter that will permit it to engagefrictionally within `the bore of a tube I6. This tube I6 is preferablymade out of arigid material, such as metal, Vand has an externaldiameter approximating that ofthe bore in the extension I2. By insertingthe `Vtube I6 within the bore of this stem extension I2, frictionalengagement is had within that bore, lparticularly by that part of thetube I6 which surrounds the end I5 of the mouthpiece I4 so that themouthpiece 'I4 may be removably seoured in position and there maintainedin the desired relation with the bowl ID.

The tube I6 is cut away ahead o-f the mouthpiece end I5, Figs. 2 and 3,to leave a longitudinal opening into the tube. Referring to that form ofthe tube as shown in Figs. 2 and 3, in cutting away the upper part ofthe tube I6, a tongue I'I is left and given a periphery that will causethe tongue to t snugly against the wall o the tube in an inclinedposition when that tongue is pushed down into the tube to have its lowerend come into contact with the floor of the tube. The tongue I'I thusforms a partition across the tube I6 including upwardly and outwardlytoward the tube end. Then the tube is provided with a groove I8 presseddownwardly in that part of the top side of the tubebetween the tongueand the end of the tube.

.In practice, the mouthpiece I4 is removed to The tube le is then 1 upand ll the spacethereabove to .the full diameter of the pipe when thepipe is being used. The tubel I6 `is then inserted within the bore ofthe stem extension I2 to bring the mouthpiece I4 into 2 its properposition, as .indicated in Figs. 1 and 2. The bowl I Il is lled withtobacco and smoked in the usual manner. The mouthpiece I4 carries theusual small diameter passageway 2D therethrough. Should all of thetobacco be consumed within the bowl I0, the tobacco within the tube IGwill not become ignited from the last burning tobacco in the bowl I byreason of the fact that the tongue I'l serves effectively as a partitionto form a small chamber in the front end of the tube I5 free of tobaccoor ltering medium so that an airgap is thereby had between the pipe bowllil and the filtering medium within the tube I5. The groove I8 is ofsuiicient length to prevent any substantial transfer of heat from thepipe bowl to the lteringmedium.

Should for any reason the small hole I3 in the bottom of the bowlIbecome clogged, the mouthpiece I 4 may be axially revolved so as torock the tube end across .fthehole I3 `and thereby clear the hole. Thetube I6 may be withdrawn by pulling out on the mouthpiece Ill and thenthe ltering material knocked out. Not only do the shoulders I9 at thesides of the groove I8 on the forward end of the tube I6 provide anexcellent means 4for cleaning the interior of the pipe, but they alsomay be used eiectively by inserting the tube l-G downward-ly within thebowl I0 to clean out the bowl itself Referring to the modified form ofthe lter carrying tube as shown in Figs. 5 and 6, the forward end of thetube I6 may be formed in any other suitable manner to accomplish thesame result as above indicated, such for example as by cuttinglongitudinally through the top of the front tube portion and thenbending one side of the tube downwardly and inwardly to form theretaining nger 2| which enters in a V-slot 2,2 formed in a plug 23 thatserves as a partition member in place of the tongue I1. The plug 23preferably has its inner face sloped upwardly from the iloor of the tubeand forwardly. 'The plug is so proportioned in size as to leave a smallchamber 24 in the front end of the tube as indicated in Fig. 5. Thisform leaves a sharper cutting shoulder 25 4at the front end of the tube.In any event, whether either form be employed, the ltering medium can bethrown out of the tube very readily by giving it a jerk to allow thematerial to slide on up over the tongue I 'I or the partition wall 23 sothat no gouging or picking around in the tube I6 is required to cleanit.

Should for any reason the tube I6 through use become loose within thebore of the stem extension I2, the free sides of the tube I6 between thefront and rear ends thereof may be spread laterally so as to engage thewall of the bore more securely` Thus it is to be seen that I haveproduced a very simple yet eiiective pipe construction, free of theusual difficulties, all without any complicated mechanisms or minutepassageways, and while I have herein shown and described the inventionin the one precise form, it is evident that structural variations may beemployed, such for example as varying the formation of the cutting endof the tube and the forward partition, etc., all without departing fromthe spirit of the invention and I, therefore, do not desire to belimited to that precise form beyond the limitations as may be imposed bythe following claims.

I claim:
